IMPROVEMENT IN SAW-JOINTERS.

Specification forming part of Letters Patent No. 148,898, dated March24, 1874 application filed July 19, 1873.

To all whom it may concern:

Be it known that I, GEORGE S. PRINCE, of West Salisbury, in the countyof Merrimack and State of New Hampshire, have invented a new andImproved Circular-Saw Jointcr, of which the following is aspecification:

My invention relates to means for securing and adjusting a file-plate inthe head of the jointer-frame, as hereinafter described.

Figure l is a front elevation of my improved saw-jointer. Fig. 2 is aside elevation of the jointer, also a portion of a saw. Fig. 3 is atransverse section taken on the line a; 00 of Fig. 2. a

A represents a short, flat bar of steel or iron, not quite as long asthe radius of the saw. It has a crotched end, B, adapted to rest on thesaw-arbor or on the collar G, as shown in Fig. 2. It also has clips, 1),attached to the edges to form guides, in which another short plate, E,is fitted to slide forward and back. This plate E has a head, F, on theouter end, in which a short, flat file, G, is secured by set-screws H orkeys, so that the points of the teeth of the saw may be caused to" runagainst the sides and be filed off to dress them all to the same length.An adjusting-screw, J, is arranged in the stud K of the plate A and thenut L of the plate E, so as to slide the latter forward and back toadjust the J serves both to adjust the bar E on the other bar, A, and tohold it fixed in any position to which it may be adjusted, while thescrews H are so arranged with the head F that the file G may be adjustedhigher or lower on either side, or at either end, according to the bevelrequired to be given to the saw-teeth.

Having thus described my invention, I claim as new and desire to secureby Letters Patent In combination with the head F of the jointer, thefile-plate Gr and screws H, arranged as shown and described, wherebysaid plate may be adjusted at various angles, as specified.

GEO. S. PRINCE.
